Electric vehicles (EVs) are simplest way to replace fossil fuel powered vehicles. EVs are relatively cheap, have little environmental impact and are a technology which is available here and now. Using all electronic control board and two power boards, a high power EV drive system was designed and constructed (designed for the vehicles tip to 100 kW). The controller uses power IGBT module and microcontroller technology to simultaneously control two DC series motors. The driver controls direction of motion and causes differential speeds of motors relative to steering rod and acceleration pedal position. Driver simulation ill e MATLAB proved that the required conditions of the problem were satisfied by PID controller; and the optimum values for the control parameters K-p, K-i and K-d were found to be 320, 350 and 40, respectively. The result of simulation for these motors indicated that for start lip a high torque is available.
